On one hand the article oversells how weir this is. For electric charge this is quite usual https://en.wikipedia.org/wiki/Multipole_expansion and magnetism is not so different.

On the other hand, some of these materials get actual applications after a few years. At least for me, it's very hard to guess if this one will be useful.
